Abstract

A wireless networking method includes providing a plurality of different sets of wireless links and a plurality of wireless nodes. The nodes are in mutual bi-directional wireless communication via the wireless links. Each of the links enables the communication between a respective pair of the nodes. Information is transmitted to a selected one of the nodes from each of other ones of the nodes via a first of the sets of the wireless links. The step of transmitting information to the selected one of the nodes from each of other ones of the nodes is repeated via each of other ones of the sets of the wireless links, respectively.

Claims

1. A wireless networking method, comprising the steps of:

providing a plurality of different sets of wireless links;

providing a plurality of wireless nodes, the nodes being in mutual bi-directional wireless communication via the wireless links, each of the links enabling the communication between a respective pair of the nodes;

transmitting information to a selected one of the nodes from each of other ones of the nodes via a first of the sets of the wireless links, the transmitting step including;

transmitting a first signal from one of the child nodes to one of the parent nodes, the first signal including first information; and

transmitting a second signal from the one parent node to the selected one of the nodes and to the one child node, the second signal including the first information;

repeating, via cyclical use of each of other ones of the sets of the wireless links, respectively, the step of transmitting information to the selected one of the nodes from each of other ones of the nodes, the other ones of the nodes including parent nodes and child nodes; and

selecting the different sets of wireless links such that each of the parent nodes receives an approximately equal number of the transmissions of the information from the child nodes.

2. The method of claim 1 comprising the further step of repeating indefinitely the transmitting and repeating steps.

3. The method of claim 1 wherein the selected one of the nodes comprises a base station node.

4. The method of claim 1 wherein the transmitting step includes using more than one frequency channel.

5. The method of claim 1 wherein at least one of the sets of wireless links is used more frequently than at least one other one of the sets of wireless links in transmitting the information.

6. A wireless networking method, comprising the steps of:

providing a plurality of wireless nodes including a grandparent node, a parent node, and a child node;

transmitting a first signal from the child node to the parent node, the first signal including information;

using the parent node to transmit, in response to the parent node receiving the first signal, a second signal to each of the grandparent node and the child node, the second signal including the information; and

treating reception of the second signal at the child node as an acknowledgement signal to the child node that the first signal was received by the parent node.

7. The method of claim 6 wherein the second signal includes at least one bit that both is included in the information and serves as at least a portion of an acknowledgement signal to the child node that the first signal was received by the parent node.

8. The method of claim 6 wherein the providing step includes providing a plurality of parent nodes and a plurality of child nodes, the method comprising the further step of transmitting a plurality of signals from the child nodes to the parent nodes via alternatingly used communication paths.

9. The method of claim 8 comprising the further step of selecting the alternating communication paths such that each of the parent nodes receives an approximately equal number of the plurality of signals.

10. The method of claim 8 wherein the step of transmitting a plurality of signals from the child nodes to the parent nodes includes using a plurality of frequency channels.

11. The method of claim 8 wherein at least one of the communication paths is used more frequently than at least one other one of the communication paths.
